Safety And Efficacy After Implantation Of The Femtis Comfort Lens Using The Lensar™ Laser System In A Follow Up Of Five Years - A Series Of 30 Eyes

Proper centration and positioning of the IOLs is fundamental to achieve perfect outcomes with premium IOLs. Due to the highly predictable size and position of capsulotomy possible with femtosecond laser, laser assisted capsulotomy can improve the centration of the IOL especially with the modern types of Femto lenses.  The FEMTIS Laser Lens (Teleon) has a special haptic system, which allows the lens to clamp into the capsulotomy. Long term safety is always a concern in new technologies. Therefore we investigated the outcome of patients after a postoperative period of five years. We included 30 eyes of 15 patients.

Study included 30 eyes (15  patients) with cataract that underwent FLACS. Mean age at surgery was 72.5 ±4 years. Femtosecond laser assisted capsulotomy of 4.8mm centered on the pupil center and lens fragmentation were performed using the LENSAR™ femtosecond Laser System. The additional haptics were used to clamp the IOL into the capsulotomy. Up to five years postoperatively the patient where examined especially in mydriasis and the centration and fixation in the capsulotomy was examined and photo documentation was performed. Regarding the additional haptics anterior to the capsulotomy signs of iris shaving and secondary glaucoma were searched. Also the history was documented e.g. regarding events of iris capture.

 

No postoperative lens design related complications like an iris capture e.g. occurred,  The Femtis Comfort IOL was well centered in all eyes. Especially no signs of problems regarding the additional haptics enclaved in the capsulotomy or problems with the anterior capsule were notice. No signs of iris shaving or secondary glaucoma were noticed. Independence of glasses for far and Intermediate distance was high even five years after the operation. Binocular DVA was in average 0.0 LogMAR and binocular IMVA 0.1 LogRAD. Refraction showed no significant changes over the postoperative period.

 

The implantation of FEMTIS Comfort laser lens was found to be safe and effective during the study follow-up of up to 5 years. The centration of the lens was independent of influences of the capsular bag. Refractive outcome was stable over time. The study  determines the long-term safety and efficacy of the new IOL and shows the advantages of the combination of FLACS and new Femto lens designs.
